Visit to Parc des Buttes-Chaumont

situated in northeastern Parsi,  in the 19 quater, occupying 61 acres,  is the fifth-largest park in Paris. It was opened in 1867, late in the regime of Emperor Napoleon III.  The park has 5.5 kilometres (3.4 miles) of roads and 2.2 kilometres (1.4 miles) of paths. The most famous feature of the park is the Temple de la Sibylle, inspired by the  Temple of Vestain Tivoli ,  Italy, perched at the top of a cliff fifty metres above the waters of the artificial lake.

The park took its name from the bleak hill which occupied the site, which, because of the chemical composition of its soil, was almost bare of vegetation – it was called Chauve-mont, or bare hill. The area, just outside the limits of Paris until the mid-19th century, had a sinister reputation; it was close to the site of the Gibbet of Montfaucon,  the notorious place where the bodies of hanged criminals were displayed after their executions from the 13th century until 1760. After the 1789 Revolution, it became a refuse dump, and then a place for cutting up horse carcasses and a depository for sewage. The director of public works of Paris and builder of the Park, Jean-Charles Alphand, reported that "the site spread infectious emanations not only to the neighboring areas, but, following the direction of the wind, over the entire city."

Another part of the site was a former gypsum and  limestone quarry, mined for the construction of buildings in Paris and in the United States.  This not-very-promising site was chosen for the site of a new public park for the recreation and pleasure of the rapidly growing population of the new 19th and 20th arrondissements of Paris, which had been annexed to the city in 1860.

The work on the park began in 1864, two years were required simply to terrace the land. Then a railroad track was laid to bring in cars carrying two hundred thousand cubic meters of topsoil. A thousand workers remade the landscape, digging a lake and shaping the lawns and hillsides. Explosives were used to sculpt the buttes themselves and the former quarry into a picturesque mountain fifty meters high with cliffs, an interior grotto, pinnacles and arches. Hydraulic pumps were installed to lift the water from the canal of the Ourcq River up the highest point on the promontory, to create a dramatic waterfall.
